Obsidian LanguageTool Plugin

This plugin for Obsidian.md integrates LanguageTool to provide advanced grammar and spellchecking.

This is a fork of the original obsidian-languagetool-plugin, with the following changes:

• Added support for synonyms and mother tongue
• Add tooltip button for disabling rules
• Remove old code and clean up the codebase, following Obsidian's best practices
• Fix multiple bugs and freezes

Note: if you are worried about the privacy of your notes, you should self-host LanguageTool locally on your PC or on a server. If you decide to self-host the service, you must change the link in the configuration accordingly.

Installation

1. In Obsidian, under Settings / Community plugins, turn off "Safe mode" (read the safety warning).
2. Click the Browse button for Community plugins.
3. In the top-left search field, search for "LanguageTool". Click the Install button.
4. After the installation is successful, click Enable to enable the plugin.

Setting Up & Use Case

After installing and enabling the plugin, you can set up hotkeys (under Settings / Hotkeys), which can be found under the description "LanguageTool" through the Filter search field, to find specific hotkey functions quicker. Ensure no conflict exists with existing hotkeys and the spellcheck function within Obsidian if enabled (Settings / Editor / Spellcheck ON/OFF).

• "Check Text" checks the whole document in view if no text is selected. If you want to check only a word, sentence, or paragraph, select the text of choice and press the keyboard shortcut you have previously set. Click on the red underlined word that LanguageTool identified as a possible spelling mistake to get corrective suggestions in a popover window, with the option to add the word to a personal dictionary.
• "Clear Suggestions" clears the document or selected text of all red underlines from words or passages that were not corrected or changed.
• "Toggle Automatic Checking" toggles ON/OFF the automatic spellchecking function as you write or change the document's contents.

LanguageTool tries to auto-detect the language used. Selecting a specific language (under Settings / LanguageTool / Static language) usually is not necessary. This feature enables the user to spellcheck in different languages within the same document (e.g., a dissertation written in English with quotes in a foreign language), which is ordinarily not possible with the built-in spellcheck function of Obsidian.

You can also specify a document language in the properties of a document. Just add a property (usually crtl+;) with the name lt_language and a language code (en-US, de-DE, ...) as value.

Custom Spellchecker Dictionary: You can add words to this dictionary directly from the editor and remove them again in the Obsidian settings (Settings / LanguageTool / Spellcheck Dictionary).
